"...For example, Eastern Europe has a different gauge railroad than Western Europe does so moving supplies is more difficult. So we are learning great lessons like that”
Who's this nitwit again?
Ummm...seems that's a lesson well-learned from the German Rail Administration during Barbarossa. Laid some serious amounts of re-gauged track throughout the war in the east.
Pretty common knowledge at this point and seriously diminishes, IMV, the quality of this "study".
